  2. Ozonolysis - Wikipedia

    en.wikipedia.org/wiki/Ozonolysis

    In organic chemistry, ozonolysis is an organic reaction where the unsaturated bonds are cleaved with ozone (O 3). Multiple carbon–carbon bond are replaced by carbonyl (C=O) groups, such as aldehydes, ketones, and carboxylic acids. The reaction is predominantly applied to alkenes, but alkynes and azo compounds are also susceptible to cleavage.

  3. Azeotrope tables - Wikipedia

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

  4. Methylpentene - Wikipedia

    en.wikipedia.org/wiki/Methylpentene

    Methylpentene is an alkene with a molecular formula C 6 H 12.The prefix "methyl-" is derived from the fact that there is a methyl(CH 3) branch, the word root "-pent-" is derived from the fact that there are 5 carbon atoms in the parent chain, while the "-ene" suffix denotes that there is a double bond present, as per IUPAC nomenclature. [1]

  5. Olefin metathesis - Wikipedia

    en.wikipedia.org/wiki/Olefin_metathesis

    Formerly the reaction had been called "olefin disproportionation." In this reaction 2-pentene forms a rapid (a matter of seconds) chemical equilibrium with 2-butene and 3-hexene. No double bond migrations are observed; the reaction can be started with the butene and hexene as well and the reaction can be stopped by addition of methanol.

  6. Pentene - Wikipedia

    en.wikipedia.org/wiki/Pentene

    As of 2010s, the only commercial manufacturer of 1-pentene was Sasol Ltd., where it is separated from crude by the Fischer-Tropsch process. [2] 2-Pentene has two geometric isomers: cis-2-pentene and trans-2-pentene. Cis-2-Pentene is used in olefin metathesis.

  7. 2-Pentyne - Wikipedia

    2-Pentyne can be synthesized by the rearrangement 1-pentyne in a solution of ethanolic potassium hydroxide or NaNH2/NH3. [1] References

    en.wikipedia.org/wiki/Benson_group_increment_theory

    As determined by the enthalpies below the corresponding molecules, the enthalpy of reaction for 2-methyl-1-butene going to 2-methyl-butane is −29.07 kcal/mol, which is in great agreement with the value calculated from NIST, [15] −28.31 kcal/mol. For 2-butanone going to 2-butanol, enthalpy of reaction is −13.75 kcal/mol, which again is in ...
